DHA

DHA is the structural counterpart to EPA within omega-3.

While EPA is often discussed in terms of signaling, DHA is more closely associated with physical composition — particularly in the brain and retina.
It is a major component of neuronal membranes, which gives it a different role in formulation.

Because of this, DHA is not simply “another omega-3.”
Its relevance depends heavily on context.

At a high level, evaluation comes down to three signals:

• Absolute DHA dose — the amount delivered relative to intended use
• Balance with EPA — whether DHA dominates, complements, or is diluted within the formulation
• Formulation intent — whether the product is designed around structural support rather than general omega-3 labeling

DHA is often emphasized in products targeting cognitive or visual contexts.
But like EPA, its presence alone does not establish quality.

A label that includes DHA does not explain how, or why, it is there.
